@Article{, title={Relation Between Ocular Pressure and Cup to Disc ratio In Glaucoma}, author={Abdul Kareem Thamer Mohammad}, journal={Dijlah Journal مجلة دجلة}, volume={2}, number={2}, pages={22-31}, year={2019}, abstract={Glaucoma is an irreversible optic neuropathy associated with characteristic cupping of the optic nerve head with corresponding nerve fiber loss and peripheral and ultimately center visual field defect. To assess this disease the relationship of ocular tension and cup/disc ratio in glaucoma patients need to be determined. The retrospective study was done with 132 eyes of 66 patients visiting glaucoma clinic at Ibn-Al-HaethamTeaching Eye Hospital, beginning in November 2016toApril 30 2017 for the above subjects, ocular tension ,by measuring the cup/disc ratio and visual acuity . The present study was showed that, an important relation of ocular tension and cup/disc ratio which revealed that increasing ocular tension a accompanied with increasing cup/ disc ratio irreversibly. So, when the intraocular pressure is treated with medicine for reducing its levels, the value of the cup/disc ratio is not affected (remain in its high level). It has been noticed that there is reversely relation between cup/disc ratio and visual acuity, and glaucoma incidence was increased with increasing the age of patients i.e. as the population grows older , the prevalence of glaucoma raises.
